Fuel Issue

[Tanuki]

I am leaking fuel.

It is not a constant leak. When I am at work the car sits for about 8 hours straight and not a drop (sometimes a little, but not often). I go home and park the car in the garage. When I wake up the house smells like fuel. I go out and there is about a pint of fuel that has leaked out on the garage floor. I check the lines and there is nothing still dripping. The leak is coming from the Left side somewhere as the puddle is always on that side.

Any ideas as to how or why? I would say it was a fitting or bad fuel line if it was consistent, but where it's not, it is hard to find and not making a whole lot of sense.

I am thinking maybe a stuck fuel float in the carb?

After some research, I am thinking it is the mechanical fuel pump.

I assume the drip is up under the engine.

I thought they switched to electric fuel pump a long time ago. Or maybe they started with electric pumps and switched to mechanical.

Either way, I never liked mechanical pumps on the A series. That comes form a mechanical pump both on my Bugeye and an Austin America, and both of them interfered with the headers making them non-usable.

The leak may however be from the float like you say. But since there are many places it could leak from, you're just going to have to do some detective work. Of course the fuel evaporates before you get a chance to see it.
